April: The Winter Swell Machine Switches Off
April sees the winter swell machine switch off. Average swell height drops to 2.3ft (0.7m) and average period to 4.9s, right in the choppy, messy range. The favorable S/SSW/SW window, while still 25.7% of the directional total, is heavily weighted toward the 0.5-1m class, which means small, groveling conditions at best. NW swell still dominates at 19.6% and combines with WNW, W and WSW energy to fill out the background sea state, but this is energy hitting at the wrong angle for the SSW-facing bight. Wind quality takes a step back as well: ideal offshore wind drops to 13%, with stronger NNW and NW flow becoming prominent as the Greek landmass warms. A 1-2ft (0.3-0.6m) wave will be the norm, but an occasional clean 2ft day can still happen when a spring cutoff low drifts over the southern Ionian. Water temperature is 16.2°C and air temperature 15.6°C, while precipitation drops to 1.55mm/day.
